The rapid growth in the smart sensor technology (SST) has enabled easier and more economic construction of the
structural health monitoring system (SHM). Nevertheless, there is no distributed damage detection algorithm for efficient
usage of the computation power of the SST. Therefore, this study aims at developing a new distributed damage detection
algorithm suitable for the smart sensor system for the SHM. The algorithm suggested in this study utilizes the damping
ratio of a structure, using the structure's energy dissipation ratio. In other words, each smart sensor installed to the
structure analyzes the response signals from the structure into a damping ratio, which in turn is computed into an energy
dissipation ratio, using the smart sensor's ability to handle data. Thus, this method detects the damages and locations of
the damages in a structure using the changes in the energy dissipation ratio it has calculated. In this study proves the
usefulness of the developed energy dissipation ratio by numerical simulation.
